MACHINE FOR MAKING PAPER TUBES,

SPECIFICATION forming part of Letters Patent No. 373,655, dated November22, 1887.

Application filed June 2, 1886. Serial No. 203,004. (No model.)

To all whom it may concern:

Be it known that I, THOMAS GRANGER, of the city, county, and State ofNew York, have invented a new and useful Improvement in Machines forMaking Paper Tubes, of which the, following is a full, clear, and exactdescription.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of inyiinproved machine, parts being brokenaway. Fig. 2 is a sectional side elevation of the same, taken throughthe line :0 as, Fig. 1. Fig. 3 is a sectional side elevation of thesame, taken through the line 3 y, Fig. 1. Fig. 4 is asectional plan viewof a part of the same. Fig. 5 is a side elevation of a part of the same,partly in sec tion, and parts being broken away.

The object of this invention is to provide machines for making papertubes, constructed in such a manner that the paper tubes can be madequickly, and which at the same time shall be simple in construction andconvenient in use..

The invention consists in the construction and combination of variousparts of the machine, as will be hereinafter fully described.

A is the frame of the machine, and B is the feed-tab1e placed in frontof the said frame.

In hearings in arms or brackets formed upon or attached to the front ofthe middle part of the frame A revolves a short shaft, 0. To the ends ofthe short shaft 0 are attached the inner ends of the mandrels D, uponwhich the paper tubes are formed, and the outer ends of which are freeand unsupported, so that the paper tubes, when formed, can be readilyremoved.

Upon the middle part of the shaft 0 is placed a loose pulley, E, towhich motion is given by an endless belt, F, from any convenient power.To the shaft 0 at one side of the pulley E is secured a sliding clutch,G, the hub of which has an annular groove, H, formed in it to receivethe forked end of the lever l. The lever I is pivoted to a support, J,attached to the feed-table B, and its free end projects into such aposition that it can be readily reached and operated to move the clutchG and. throw the pulley E into and out of gear with the shaft 0. Thelever I is secured in either position by placing it upon one or theother side of the stop K, attached to the feed-table B.

The paper is held in place while beingformed into rolls upon theinandrels D by endless belts L, passing around the lower, inner,and'upper sides of the said mandrels, passing around the small guide andpressure rollers M, journaled to the outer ends of the arms N, pivotedto the frame A below and above the level of the said mandrels and aroundthe guide-rollcrs 0, also journaled to the frame A above and below thelevel of the said niandrels. the arms N are rigidly attached to shaftsP, which rock in hearings in the frame A.

To the inner ends of the shafts P of each pair of arms, N, are attachedtwo gcar-wheels, Q, the teeth of which mesh into each other, so that thesaid shafts will be rocked together, but in opposite directions.

To the inner end of each lower shaft, P, or to each lower gear-wheel, Q,is attached a short crank, R, to which is pivoted the upper end of aconnecting-rod, S. The lower ends of the connecting-rods S are pivotedto the inner ends of the foot levers or treadles T,the

outer ends of which project at the front of the machine, so that theycan be readily reached and operated by the operator to swing thepressure-rollers M away from the mandrels D or to swing them against thesaid mandrels with any desired pressure.

Upon the upper arms, N, are formed extension-arms U,to the outer ends ofwhich are journaled the pasteapplying rollers V, which, when thepressurerollers M are swung away from the mandrels D, are swung intocontact with the rollers XV, journaled to the ends of the pastetroughsX, so that the lower parts of the said rollers will be immersed in thepaste in the said troughs. The troughs X are attached to the frame A andare provided with scrapers Y to remove the surplus paste from the saidrollers before the paste'applying rollers V come in contact with them.The rollers V are made of such a size that one revolution of the saidrollers will apply paste to the paper Z from which the tubes are to bemade The inner ends of from a point at a distance from the inner end ofthe said paper equal tothe circumference of the mandrels to the outerend of the said paper, so that the inner layer of the paper tubes willbe free from paste and the succeeding layers will be securely cementedin place. The arms U are made of such a length that the rollers V whenlowered will come in contact with the paper Z at the proper distancefrom its inner end. The top of the feed-table B, beneath the point wherethe roller V comes in contact with the paper Z, has a recess, a, or aslot formed in it into which the said paper is depressed by the saidroller V, the lower part of the face of the said roller being a littlebelow the surface of the said table when the said roller comes to thelimit of its downward movement, so that the paste-applying roller willnever come in contact with the said feed-table or smear it with paste.

To the table B at the edges of the recesses or slot a are pivoted smallrollers 12 to lessen the strain upon the paper as it passes over thesaid edges.

The long paper tubes,when completed and while still upon the mandr'elsD, can be cut into short tubes by a series of circular cutters, c,placed upon shafts d and kept at the required distance apart by tubularwashers e, placed between them upon the said shafts, or by othersuitable means. The ends of the shafts d arejournaled to the ends ofarmsf, attachedto the shafts g, which are journaled to the table B, andto which are attached short crank-arms h. To the ends of the crankarms hare pivoted the upper ends of connecting-rods i, thelower ends of whichare pivoted to foot levers or treadles j, so that the cutters 0 can beswung up against the paper tubes upon the mandrels D by operating thesaid treadles, and can be allowed to swing away from the said tubes whennot required for use.

The paper tubes, when completed, can be stripped from the mandrels withthe hand or by means of rings k, sliding upon the said mandrels andplaced at their inner ends. The rings 7c have annular grooves Zformed inthem to receive the forked. ends of arms m, the bases of which aredovetailed and slide in dovetailed grooves 11, formed in the inner edgev of the top of the table B, or in bars attached to the said table-top.To the outer parts of the bases of the arms m are attached the innerends of cords 0, the outer ends of which are wound around and attachedto drums or pulleysp, attached to or formed upon the inner ends of theshafts q,journaled to the end parts of the table B, and having cranks 1attached to their outer ends. To the inner parts of the bases of thearms at are attached the upper ends of cords s, which pass overguide-pulleys t, pivoted to supports attached to the table B. To thelower ends of the cords s are attached weights at of sufficient gravityto draw back the arms in and rings after being moved outward byoperating the cranks r to strip the paper tubes from the mandrels'D.

The paste-rollers W are driven from the driving-pulley E by an endlessbelt, 12, which passes around apulley, w, attached to the saiddrive-pulleyEand around a pulley,x, attached to-the journal connectingthe inner ends of the said rollers W.

In using the machine a paper tube is formed upon one mandrel and allowedto remain under pressure while a second tube is being formed upon theother mandrel, which in turn is allowed to remain under pressure untilthe first tube has been removed from the first mandrel and a new tubeformed upon it, so that the outer layers of the tubes will be presseddown smoothly and will be kept under pressure until securely cemented inplace.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. The combination, with a mandrel havingone end unsupported, of an endless belt arranged in connection with saidmandrel, fixed rollers, and rollers carried by swinging arms, one pairof said arms having extensions carrying a paste-applying roller,substantially as shown and described.

2. The combination, with a mandrel unsupported at one end, of a ringloosely encircling said mandrel at its supported end, an arm applied tosaid ring and sliding upon the feedtable, the handled or crank shaftconnected to said arm to impart to it movement in one direction, saidarm, with the ring, having an automatic return movement, substantiallyas shown and described.

3. In a machine for making paper tubes, the combination, with the frameA, the feed table B, and the mandrel D and its driving mechanism, of theendless bands L, the guiderollers O, journaled to the frame A, the guideand pressure rollers M, the arms N, carrying the said rollers M, theshafts P, journaled to the frame A, carrying the said arms N, andconnected by gear-wheels Q, and the arm R, connecting-rod S, and treadleT, for operating the said guide and pressure rollers, substantially asherein shown and described, whereby the paper will be rolled firmly andsmoothly upon the said mandrel, as set forth.

4. In a machine for making paper tubes, the combination, with thefeed-table B, having recess a, the roller \V, revolving in thepaste-trough, and the arms N, carrying the guide and pressure rollers M,of the arms U,

carried by the said arms N, and the roller V, carried by the said armsU, substantially as herein shown and described, whereby the with drawalof the said pressure-rollers from the mandrel will raise the saidpaste-applying roller to receive paste, and applying the saidpressure-rollers to the mandrel will lower the said roller to paste thepaper, as set forth.
